Frequently Asked Questions

Cubes

What is the best cube?

It really depends on your personal preference. This "What Cube Should I Get?" thread on the forums has updated recommendations for varying budgets and puzzles types, and is the best place to start. It can be overwhelming with the amount of different cubes on the market, but that thread will help you select a puzzle for you.

Where can I buy cubes?

This thread has links to various online puzzle shops around the world.

How do I lubricate my cube?

You can either take a piece or two out and spray the lubricant in directly, or disassemble and fully spray the lubricant on every piece with sweeps. There are many tutorials in youtube if you need help. Also, check youtube for techniques to lubricate big cubes.

The best lubricants tend to be silicone based. Products like Jig-a-Loo and CRC Heavy Duty Silicone spray are very popular among cubers. There is a lubricant made specially for cubing which can be bought at Puzzleproz. You should never use WD-40 lube on your cube as it contains petroleum distillates which can damage the plastic. Some people do use petroleum jelly to break in really stiff cubes such as storeboughts, but it should never be used as lube.

Are there timers on the Internet?

Yes, there are many. CSTimer is one of the more popular timers and works well.

Can I download a timer for my computer/phone/PSP?

CCT (CALCubeTimer) in JAVA (jar file), here, is very popular with many features like being able to connect a speedstacks timer with a data port to the computer and use it with CCT. Last update is version 0.9.5 (nov/2010). No longer maintained.

iPhone and iPod touch, iiTimer (a port of qqTimer that works very well).

Android, jjTimer and JustInTime are both good options. Other with many features is Sune Timer (scrambles, algorithms for CFOP, WCA Regulation, etc!)

Note that for solves that take more than 15 seconds, a simple analog clock will work just fine if you don't need precise timing.

Where can I find a scramble generator?

Most speedcubing timers include scrambler generators.
If your timer does not have scrambles, you can use this page to find a scramble generator for your puzzle. The Web-based Software Wiki page also has up-to-date info on online scramblers.

What is standard deviation?

http://en.wikipedia.org/wiki/Standard_deviation
In probability theory and statistics, standard deviation is a measure of the variability or dispersion of a population, a data set, or a probability distribution. A low standard deviation indicates that the data points tend to be very close to the same value (the mean), while high standard deviation indicates that the data are spread out over a large range of values.

Competitions

Where are the rules for WCA competitions?

How fast do I need to be to compete?

There's no requirement for speed to participate in most competitions. Even high level competitions like the US Nationals are open to all, if you see a time listed for "prequalification", this is a time that allows you to skip the qualifying round. If you are slower than that time you will still be allowed to take part in the qualifications.

If you have the opportunity to attend a competition, even if you're not very fast, most experienced competitors would advise you to go for the social interaction and experience.

Methods

What is the fastest method?

There is no ultimate method, its really down to personal preference. The most popular speedcubing method is currently Fridrich, although other methods such as Petrus, Roux and ZZ are rising in popularity. Fridrich is currently used by many of the top speedcubers, and is as such believed to be the fastest method. However, others attribute this to its popularity. The most obvious/natural progression from the beginner LBL method is Fridrich, which may explain its popularity. Being the most popular means it gains the most support and development, and is also more likely to be adopted by a talented cuber. More info can be found in the speedsolving forums, where this often comes up as topic of debate.

What is the easiest method?

The easiest method to learn is probably the beginner's layer-by-layer (LBL) method in which you solve the first, second, and the finally the last layer one by one. It's pretty basic, therefore easy to learn. However, this method however is relatively inefficient and is hard to achieve good times with. Other beginner methods exist, focusing on lower numbers of algorithms and/or more intuitive solving. Compared to the others, the LBL method has the easiest transition to the popular Fridrich speedcubing method.

What is the method that uses the fewest moves?

The most popular method for Fewest Moves solving is the Petrus method. Although it is designed for speed, it tends to have a very good move efficiency compared to other methods. The Heise method is another method that was designed specifically for move efficiency rather than speed. It is highly intuitive and very difficult to master. Other methods can be still be made efficient if you plan your moves carefully.
More info on FM can be found on the Fewest Moves page.

Should I learn algorithms for F2L or learn it intuitively?

That is entirely your choice. Learning the algs isn't entirely hard since most cases can be seen and understood by practicing the algorithms, and it won't take as much thinking when solving. If you do it intuitively, it will take practice to be able to do with speed and efficiency.

Most people choose to learn intuitively and with some practice, it can be just as fast. Intuitive F2L may take more time to master but it is generally preferred because it allows for the use of advanced speed-reducing techniques such as multislotting and the use of empty slots.

How can I get faster?

Practice, practice, practice. That is the key way to get speed. Normally, with some work, your times will gradually drop without you doing anything.
(If you are around 1 minute with LBL method than you should learn a faster method.)

If you haven't, try learning an advanced method. That should help you lower your times considerably.

Work on lowering your move count, look ahead and experiment with tricks.

Learn new algorithms.

Unglue your eyes from your computer screen, pick up your puzzle, and try to get faster.

It is also helpful if you do slow solves in order to train your look ahead.

Also, don't ever use Rubik's brand for speedcubing.

I think I invented a new method, did I?

Probably not. If you haven't studied and don't fully understand the concepts behind all the major solving methods (CFOP, Petrus, Roux, ZZ, Waterman) and know the basic philosophy of the advanced variations (MGLS, ZB, Heise) then don't even bother asking.

Miscellaneous

Should I make a new web site about cubing?

Probably not unless you're actually going to provide something fresh and new and not just rehash the information already available on the 'net.
